    In fact, Cisco ACI is an amazing technology that is worth to learn, but building an ACI lab would be out of reach, as very expensive and not accessible for anyone. Furthermore, the Cisco ACI Simulator allows you to simulate faults and alerts to facilitate testing and demonstrate features.

    You can configure the policies but the data plane will not be active. OVA file deployment as it is easier and faster to deploy. You may ask one of friends who work for a Cisco partner to get it for you. OVA file is divided into four parts, so you will have to download all four files then aggregate them into one OVA file using the cat command Linux or the type command Windows.

    Once done, you just need to need to import the resulted OVA in any virtualization software. I am using VMware Workstation to proceed. Once the. It is OK to change the network as per your configuration. I have configured mine in a Host-Only network named VMnet1. The subnet range of the VMnet1 network is My machine has an IP of After the startup is complete you will be asked to provide an activation key to activate the VM.

    You will need to have this key to make your VM fully functional. What is amazing with this simulator is that it gives the same experience as the real environment. For the sake of simplicity, I will keep most of the inputs with their default values, except the part related to he management network info.

    No need for IPv6 Choose whether to use a strong password or not. When all steps are completed, you will be asked to review your configuration and once done, all processes will be started and login prompt will appear. Our ACI test environment is fully functional. We have an alert informing us that we have only one controller in our deployment.

    No worries. Here is how it works: At the startup of first controller, it will detect the leaf that it is connected to and ask us to provide some information about it, like the name and the ID. Once done, the leaf will detect the upstream spine it is connected to and will also ask some info about it.

    The spine will do the same when it will detect all leaf switches they are connected to it, and so on until all the topology is formed and the controllers have the full picture of the fabric membership.

    In our case, we have only one controller, one spine and two leafs. The APIC controller has already detected the spine it is connected to. We will use the following topology and will document the needed information accordingly Double click on the spine node ID and provide the ID and the name, then click on Update.

    After sometime, the parent spine will show up and you will need to do the same. Once all the steps are completed, you will have full test environment to play with.

    You have now your ACI lab environment ready to be used. I hope you enjoyed reading this article as much as I did while writing it!

    Cisco ACI Training

    It uses some examples from the lab environment to show you how the things look like when you start to work with ACI. There are other articles in the works which will be online soon and which will go in details through the real configuration of ACI and best practices while doing it.

    Cisco ACI is a datacenter network Fabric. It actually means that it is a networking system of more networking L3 switches that have a modified, next-generation OS which enables them to be centrally provisioned and configured through APIC controller to work as one device from access port perspective. In the picture above we are connected to Web GUI of APIC controller cluster and we see lab environment build with two Leafs and Two Spines minimal configuration with two APIC controllers in a cluster production environment would have 3 or 5 of controllers in a cluster.

    This is a lab example where everything was left by default. You click on register the Leaf to the Fabric and give the Leaf a number Leaf are usually numbered from … and Spines are from …. It will give him a hostname, configure in-band mgmt loopback and also it will give him another loopback which will later be used in IS-IS routing protocol which is used to route overlays for your data plane.

    IS-IS has also configured automatically in this first time Leaf configuration and you do not need to see all those things. You continue to register the Spines as you did with the Leaf taking care that the numbering is in order with your rack switch positioning you should take note of all serial numbers on the switches when putting them in the racks.

    Leaf and Spines after you registered them to the Fabric and they were automatically configured by APIC controller and joined to the Fabric. Now you have a big switch At this point, the Fabric is up and running. The whole fabric is working as one big switch with all Leaf ports being access ports on that huge switch system. It is like a chassis switch with multiple line cards, but here each line card is represented by one Leaf switch. This has several advantages: There are no chassis backplane issues and each Leaf is running his own OS and with that a separate control plane which is good for robustness, resilience, and stability when something goes to hell on one of the devices.

    And it is time to make this big L3 switch work and do some bridging and routing.
